Although slavery is viewed by many as an egregious practice, along with many other human rights issues, it led to several important social and political reforms in the United States. The introduction of slaves to the U.S. was received with mixed reactions by citizens across the nation. For those in the Southern states, slavery was not considered as harmful as it was in most Northern states, which eventually started a movement to create social reform for the slaves.
The introduction of slavery to the U.S. sparked several counter movements in the nation, which ranged from average citizens to prominent politicians. The first antislavery society was established in the city of Philadelphia in the mid-1770s by a group of Quaker activists. That was also the time that marked the beginning of the American Revolution and was a popular time for social change. The movement against slavery gained traction in the region, and there were more than a dozen antislavery groups operating in the 13 colonies by the late 1780s. This also led to legal reform, and caused several states in the north to ban slavery altogether. Even in states where slavery was still allowed, it was a relatively unpopular practice.
